This interactive world map visualizes global landmasses and country borders using a natural Earth projection. The visualization renders a sphere, graticule grid, land areas in teal, and interior boundaries in a lighter teal stroke. Built with React and D3 v5, it uses the `geoNaturalEarth1` and `geoPath` APIs to project and draw geographic features, while TopoJSON converts the world-atlas dataset into GeoJSON features and meshes. Styling is applied via CSS classes on SVG path elements.
